The Cincinnati Enquirer reports Cincinnati Bengals CB Tom Carter was downgraded to questionable on the team's injury report with a knee injury. The team may sign CB Kevin Kaesviharn from the practice squad to provide more depth in the secondary for tomorrow's game. Safeties Cory Hall and Chris Carter have been working this week at cornerback in case they're needed in an emergency. S Darryl Williams was held out of Friday's practice, but he's expected to play Sunday. DE Vaughn Booker, who's listed as questionable with an ankle injury, did practice Friday and will “play a lot,” coach Dick LeBeau said.

Geoff Hobson reports for Bengals.com S Tremain Mack had to start tonight's pre-season game at free safety because starter Chris Carter couldn't start because of a sore hamstring. Mack hurt his shoulder on the kickoff before the first defensive series and was replaced by JoJuan Armour because his return was questionable. Carter eventually had to play too. DB Corey Hall got thrown out of the game with Bills LB Fred Jones after an altercation midway through the second quarter.
